Researchers find black and white solution to wind turbine bird deaths

A Norwegian research team has demonstrated a relatively simple and potentially very effective way to drastically reduce the number of bird deaths at wind farms, by painting one of the three blades of a wind turbine black.

In a study conducted over 10 years at a 68MW wind farm on the Norwegian archipelago of Smøla, the research team found an average of nearly 72% reduction in annual bird fatality rate at painted turbines, compared to non-painted control turbines.

The team from the Norwegian Institute for Nature Research said the contrast painting method significantly reduced the fatality rate for a range of birds at the Smøla wind farm, but appeared to be particularly effective for raptors……..more  https://reneweconomy.com.au/researchers-find-black-and-white-solution-to-wind-turbine-bird-deaths-96526/
